Abstract

Selon l'invention, le sphygmomanomètre électronique pour obtenir des valeurs de pression sanguine sur la base de changements dans la pression d'un brassard pneumatique interne pendant le procédé de diminution de pression calcule et obtient des valeurs de pression sanguine en tant que valeurs estimées pendant le procédé d'augmentation de pression (ST5). Si lesdites valeurs estimées se situent à l'intérieur d'une plage prescrite de valeurs standards préalablement définies pour indiquer une hypertension (OUI en ST7), lesdites valeurs estimées sont affichées comme valeurs mesurées (ST8) et des actions sont terminées sans effectuer la régulation de pression interne subséquente du procédé de diminution de pression.
